DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertically elongated shell body in which a cylindrical sorting net and a frying spiral rotating in the sorting net are erected and accommodated. By supplying the selected kernels to the lower portion of the sorting net and fried by the spiraling spiral, unnecessary substances such as small grains or dust mixed in the grains pass through the small holes of the sorting net. The present invention relates to a vertical cereal sorter that discharges and removes.

[0002]

2. Description of the Related Art Conventionally, as a grain sorter, for example, one described in Japanese Patent Application Laid-Open No. 3-91417 is known. It consists of a vertically elongated shell, a cylindrical sorting net that is driven to rotate, and an erecting helix that rotates in the opposite direction inside the sorting net, and accommodates the unsorted kernels. Unnecessary substances such as small grains or dust mixed in the grains are supplied through the small holes of the sorting net and discharged by being fed to the lower part of the sorting net and fried by the filing spiral. The milled grain is discharged into a storage tank connected to the upper side of the shell.

[0003] In this type of grain sorter, unnecessary substances passing through the small holes of the sorting net are exhausted by exhaust means connected to the lower part of the shell. Is a net-like portion formed on a plate material constituting the side surface of the shell, and a step formed by the opening thereof is exposed at right angles to the direction of discharging the unnecessary matter.

[0004]

For this reason, among the unnecessary objects which pass through the small holes of the sorting net and descend along the inner surface of the shell by the airflow of the exhaust means, a step formed by the opening of the ventilation portion is included. (I.e., the mesh of the mesh portion stays in the shell), and there is a problem that frequent cleaning is required to remove the mesh.

The present invention has been made in view of such conventional problems, and a vertical cereal sorter in which unnecessary substances separated from cereal grains are completely removed without staying in the shell. It is intended to provide.

[0006]

Means for Solving the Problems The gist of the present invention to achieve this object is as follows: 1 A cylindrical sorting net (2) in a vertically long shell (1);
A rotating spiral (3) rotating in the sorting net (2) is set up and accommodated, and the supplied unsorted grains are supplied into the sorting net (2) to be lifted. Vertical cereal sorting in which unneeded substances such as small grains or dust mixed in the cereal are passed through the small holes of the sorting net (2) and discharged and removed by graining with the helical spiral (3). In the machine, the suction side of the lower part of the shell (1) is the sorting net (2).
And an exhaust means (10) for discharging inside air in the shell (1) is connected to the periphery of the shell (1).
A vertical grain sorter, characterized in that an opening (20a) on the inner side of the shell is provided with a vent (20) having a shape that looks down.

2. The vertical grain sorter according to claim 1, wherein the ventilation port (20) is a gull formed by pressing a plate material forming a side surface of the shell (1). Exist.

[0008]

When the exhaust means (10) is operated, the vent (2)
A downward airflow is introduced into the shell and is exhausted by the exhaust means (10). Unnecessary substances such as small grains or dust separated from the fine grains by passing through the small holes of the sorting net (2) by the operation of the unwinding spiral (3) cause the air current to flow into the shell (1). And is discharged by the exhaust means (10), but is vented (20) formed in the shell (1).
Since the opening (20a) on the inner side of the shell is designed to look downward, unnecessary matter does not get caught by the vent and stay in the shell.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. As shown in FIG. 1, the vertical grain sorter according to the present embodiment has a cylindrical sorting net 2 in a vertically long shell 1 erected on a base 1a and a rotating inside the sorting net 2. Squashed spiral 3
The grains are supplied to the sorting net 2 via the supply hopper 4 and are then grained by the helix 3 so that small grains or dust mixed in the grains are provided. Unnecessary substances such as are discharged through the small holes of the sorting net 2 and the remaining fines are discharged into a storage tank 5 connected to the upper side surface of the shell 1, and exhausted below the shell 1. Means 10 are connected.

A blade 6 extending in the radial direction is provided on the outer periphery of the upper end of the helix 3. The centrifugal force generated by the rotation of the helix 6 allows the grain that has risen to the upper end of the helix 3 to move in a substantially horizontal direction (see FIG. 4 (to the left) and is discharged into the storage tank 5.

The exhaust means 10 includes an exhaust blower 11 arranged to extend from the inside of the base 1a to the outside and connected to a lower portion of the shell 1, and an exhaust duct 1 connected to the discharge side.
2. Here, the exhaust blower 11
Has its suction side in the shell 1 and communicates with the periphery of the sorting net 2, and discharges the inside air in the shell 1 from the base 1a,
This is to generate an airflow for discharging unnecessary substances that have passed through the sorting net 2.

Further, a plurality of side surfaces of the shell 1 are shown in FIGS.
As shown in FIGS. 2 and 4, a vent 2 for introducing outside air into the shell 1
A plurality of 0s are formed on each side surface. This vent 20
The opening 20a on the inner side of the shell 1 has a shape which is desired to be downward, and in this case, specifically, it is a gull formed by pressing a plate material forming a side surface of the shell 1. That is, the upper portion is extruded inward while partially cutting the plate material of the shell 1, thereby forming a projecting portion 20b on the inside.

Next, the operation will be described. In order to carry out cereal sorting by the above-mentioned cereal sorter, the unsorted cereal grains may be put into the hopper 4 by operating the helical spiral 3 and the exhaust blower 11. Then, the inputted unsorted kernels are supplied into the sorting net 2 and thereafter, are lifted up by the filing spirals 3 and are raised while being bounced outward. Unnecessary materials such as grains or dust are sorted by the net 2
And is removed from the exhaust duct 12 without staying in the shell 1.

That is, the operation of the exhaust blower 11 causes a downward airflow to be introduced from the vent 20 and exhausted by the exhaust duct 12 in the shell 1. Unnecessary substances separated from the fine grains by passing through the small holes of the sorting net 2 by the operation of the filing spiral 3 are lowered in the shell 1 by this air flow and discharged from the exhaust duct 12. The vent 20 formed in the shell 1 has a shape such that the opening 20a on the inner side of the shell is viewed downward.
It does not stay at 0.

In the above-described embodiment, a gull is disclosed as a specific example of the vent, but it goes without saying that the vent of the present invention is not limited to this. For example, the pipe may be formed by curving the opening end inside the pipe penetrating the side wall of the shell 1 downward.

[0016]

According to the vertical grain sorting apparatus of the present invention, unnecessary substances separated from the cereal grains can be completely discharged without staying in the shell, so that it is not necessary to frequently clean the shell. It works.
